Authorities in Nevada are investigating after someone fired shots at a school Monday night.

Henderson police responded to Coral Academy Cadence Campus around 3:40 a.m. Tuesday, according to several local outlets. A preliminary investigation revealed that a window at the school was shattered, police said, but no injuries were reported. 

A letter sent by school staff to parents said that "the campus was shot multiple times in random places," resulting in three windows being damaged, according to Fox 5.

The school also said that local authorities had been contacted and that the incident was under investigation. Henderson police also said the investigation remained open as of Wednesday.
